Remember: Add the eighths. Then share them equally: when the total will not split, use smaller parts.

Add, then share

1
Each dot is a tub of paint. The numbers under the line count eighths of a gallon. How many eighths of a gallon of paint are there in all? eighths
2
The 17 eighths of paint are the same as how many gallons?
1 and 7/8 gallons2 and 7/8 gallons2 and 1/8 gallons
3
The paint is poured together and shared equally among the 4 tubs. How much is in each tub? Write a fraction of a gallon.
4
Is each tub's equal share more than 1/2 gallon, less than 1/2 gallon, or exactly 1/2 gallon?

Sharing Paint and Water Fairly
117 2 + 3 + 5 + 7 = 17 eighths.
22 and 1/8 gallons 16 eighths make 2 gallons, and 1 eighth is left: 2 and 1/8 gallons.
317/32 17 eighths shared by 4 is 17/8 ÷ 4 = 17/32 of a gallon.
4more than 1/2 gallon 1/2 is 16/32. Each share is 17/32, which is a little more.
511/32 The fullest tub had 7/8 = 28/32 and now has 17/32. 28/32 − 17/32 = 11/32.
6Plot 3 Plot 3 has two dots at 1, one at 4 and one at 6.
7True 12 ÷ 3 = 4 eighths, and 4/8 = 1/2.
83/4 5 + 6 + 7 = 18 eighths. 18 eighths shared by 3 jars is 6 eighths each, which is 3/4.
96 3 + 2 + 1 = 6 eighths are needed.
101-D, 2-C, 3-B, 4-A 8 eighths make 1 cup, so divide by 8: 16 → 2, 12 → 1 1/2, 20 → 2 1/2, 24 → 3.
111, 2, 4, 3 In eighths the jars hold 4, 5, 6 and 7.
